King Eiver drain the southern, northern, and eastern slopes 

 of Mount Lyell, while the Queen Eiver branch drains the 

 western slopes, we have now little difficulty in coming to a 

 conclusion regarding the occurrence of fine specks of gold in 

 the bed of the main stream further south. Mb doubt the 

 fineness of the gold would favour its wide dissemination along 

 the course of the main stream, especially when it was 

 mechanically held bound by a lighter mineral. Other localities 

 where gold was traced by Gould's party are stated to be in 

 the vicinity of Frenchman's Cap, base of Mount Arrowsmith, 

 Macquarie Harbour, Lake Dixon, Point Hibbs, junction of 

 the Franklin with the Gordon, &c. 



Mr. Gould strongly urged that this country should be more 

 thoroughly investigated, and the results at Mount Lyell 24 

 years later seem to justify his hopes and predictions. 



Since Mr. Gould's expedition left the locality no systematic 

 prospecting was done until the discovery of tin at Mount 

 Heemskirk, when prospectors made hurried examination of all 

 the more accessible localities. Amongst these prospectors, 

 Mr. Lynch, in a most persevering manner, penetrated to and 

 examined the ground now held by the King Eiver Prospecting 

 Company, where he discovered very rich auriferous quartz, 

 and from this all subsequent discoveries in the locality have 

 resulted.

Dial Bange and North- West Coast Conglomerates. — 



Massive beds of coarse conglomerates occur in many places in 

 Western Tasmania. Witli our present knowledge it would be 

 unwise to suppose they all belong to the same horizon, for 

 some of them mentioned by Mr. Gould as being associated 

 with the Gordon Group, and others forming bold ridges at 

 Frenchman's Cap, may yet prove to be more ancient than 

 those whose positions are deemed to belong to the present 

 sub-division of Upper Silurian age. The members which 

 may with some degree of safety be recognised as succeeding 

 the Gordon and Queen Eiver Groups are to be found on the 

 Dial Eange, which forms a bold conspicuous line of hills in 

 the neighbourhood of the Penguin. 



With still greater certainty may be included the coarse, 

 highly indurated conglomerates upon which the Tertiary 

 marine beds at Table Cape repose. These conglomerates 

 are as a rule composed of greatly altered water- worn pebbles 

 derived from various ancient rocks. Pebbles composed of 

 highly indurated fossiliferous bluish-grey limestones and
